J'en 26cc problem
It seems I am destined to have no luck trying gassers. First it was my ignition interference problems, now I lost my CMPro Mustang when the engine stopped during a flight.
I found that the plastic carb fuel pump connection at the base of the engine cylinder had softened with the heat & fell off. I am surprised that the manufacturers fit a plastic nipple in an area that gets hot. The engine was not too lean, if anything it was a little rich, as I was running it in. I now have the engine running again by fitting a piece of Tygon over the remaining brass stub & securing it with tie wire.
Has anyone else had this problem.

yes if your talking about the black plastic type fuel inlet to caby, your engine must be getting very hot to where the carby is positioned, work out some type of ducting so better air flow gets to the carby as well as the cylinder .

To my mind, any plastic attached to the engine cylinder is likely to melt.
The weather is getting hot here. It was in the low 40'sC the day it happened. Maybe that didn't help.
